In this paper we describe a suite of new algorithms for studying polycyclic matrix groups-algorithms for testing membership and for uncovering the polycyclic structure of the group. We also describe an algorithm for deciding whether or not a group is solvable, which, in the important context of subg

โฆ Synopsis
In this paper we describe a new algorithm for constructing a representation by integer matrices for a polycyclic group given by a finite presentation. This is a first step toward finding a practical algorithm for this problem. We used our algorithm to construct representations for various polycyclic groups. The examples which we studied included a collection of free nilpotent groups, and our results here led us to a new theoretical result concerning such groups.

The purpose of this paper is to present an algorithm for matrix multiplication based on a formula discovered by Pan [7]. For matrices of order up to 10 000, the nearly optimum tuning of the algorithm results in a rather clear non-recursive one-or two-level structure with the operation count comparab
